Dramatic Cliffs and Legends of Mie
Onigajo (鬼ヶ城), meaning “Demon’s Castle,” is a spectacular stretch of rugged coastline in Kumano City, Mie Prefecture. Facing the vast Pacific Ocean, this series of cliffs, caves, and oddly shaped rock formations has been carved over centuries by the relentless waves and wind. Today it is not only a scenic spot but also part of the UNESCO World Heritage, listed Sacred Sites and Pilgrimage Routes in the Kii Mountain Range.
The Legend Behind the Name
According to local folklore, a fearsome demon named Onigami once lived in these caves and terrorized passing travelers. The warrior Minamoto no Yorimasa eventually defeated him, and the site became known as “Onigajo,” or the Demon’s Castle. Walking through the caves and tunnels today, it’s easy to imagine the myths that gave this place its name.
Walking the Coastal Path
Onigajo features a well-maintained walkway that runs along the cliffs, offering breathtaking ocean views at every turn. The path stretches for about 1.2 kilometers, winding through caves and under natural rock shelters. Some parts are narrow and hug the cliffside, giving a thrilling sense of adventure.
- Caves and Arches: The sea-carved caves are large enough to walk through, creating natural tunnels.
- Rock Shelters: Wide overhangs of stone provide shade and a dramatic backdrop for photos.
- Ocean Views: On clear days, you can see far across the Pacific, with the waves crashing below.
World Heritage and History
Onigajo is part of the Kumano Kodo Pilgrimage Routes, a network of ancient trails that connect sacred sites in Mie, Wakayama, and Nara. Pilgrims once passed through here on their way to Kumano Sanzan, the three great shrines of Kumano. The combination of cultural history and natural beauty makes Onigajo a truly unique destination.
When to Visit
- Morning and Evening: The low sunlight casts dramatic shadows on the cliffs.
- Spring and Autumn: Comfortable weather makes the coastal walk enjoyable.
